Servo tabs for a twisty wing?

I've never flown a "twisty wing" slope glider. It's my understanding that a 'pitcheron' uses the twisty wings for both elevator and aileron function, and that a 'wingeron' uses the twisty wing for only aileron use.

In reading on forums I've learned that these gliders need powerful servos to twist the wings.

While digging through my big box of wrecked plane parts I got to looking at a glider wing half that had a servo mounted in it that operated the aileron, and I wondered if that aileron could instead be used as a 'servo tab' to twist the wing panel.
